Magnetic Chitosan Nanocomposites Derived from Industrial Solid Waste: A Promising Approach for Arsenic(III) Remediation.

ABSTRACT: In this paper, the "waste to adsorbent" strategy was proposed to synthesize Fe₃O₄ nanoparticles using the ultrasonic-assisted coprecipitation method from Bayer industrial waste. The nanoparticles were combined with chitosan (CS) to enhance their physicochemical properties. The well-covered CS on the surface of Fe₃O₄ is characterized by the nanocomposite's saturation magnetization of 50.2 emu/g, zeta potential of -14.2 mV, and specific surface area of 93.64 m²/g. The highest percentage removal efficiency was 96.73% at pH 4, with the adsorbent dosage of 0.5 g/L and the As(III) concentration of 10 mg/L, which suggests that the material is an ideal adsorbent for arsenic(III) remediation. Furthermore, the effects, kinetics, isotherms, and t
